Air line idea help?

[Bungy65]

I’m looking at setting up a John Guest air line set up for my compressor with a water trap at the end of it to help remove moisture from the airline, but as I only have a small shed I had the idea of setting the pipes up outside of the side of my shed next to a fence where he sun never reaches and it’s always just that little bit cooler but stil keep he water trap inside of the shed.
Would this work better than having all the pipework basically by the compressor?
I know copper would be better or coolers and other things, but I have limited funds and I don’t use the compressor enough to justify spending serious money on heavy duty kit.
